Here are a few photos of professionally installed brick paver driveways. The existing concrete is excavated, 4”-5” of crushed concrete base material is spread and compacted, and a layer of sand is added for leveling before 2- 3/8” pavers are installed. After the pavers are laid sand is swept into joints and a concrete border is poured to prevent migration. *There is not a single paver manufacturer who will warranty their thin pavers over existing concrete for a driveway area*
